Hand Stamp Sets

AIMS Industrial stocks 13 Gravurem metal hand stamp products covering letter sets, number sets, and a stamp holder accessory, in character heights from 1 mm up to 25 mm. Hand stamps are hardened steel punches used to strike a permanent, legible character into metal, plastic and other workpiece surfaces — the mark stays legible through painting, plating, machining oils and general workshop wear, which is why they remain the standard tool for asset numbering, part identification, serial marking and traceability stamping across Australian engineering, fabrication and maintenance workshops.

Our range covers standard letter and number sets, heavy duty sets for repeat production marking, low stress (low shock) sets and low stress dot-style sets for applications where stress-riser cracking is a concern, reverse-image sets for embossing work, a 100-piece type-in font set supplied with its own holder, an oversized 25 mm letter set for large-format marking, and a stamp holder accessory for keeping characters square and aligned while striking.

Letter sets, number sets and specialty variants

Letter and number sets

Letter sets are supplied as 27-piece kits and number sets as 9-piece kits — the standard configuration used across the trade, where a letter set covers the 26-character alphabet plus an ampersand (&), and a number set covers 0–9 by rotating the "6" stamp 180° to double as a "9". AIMS stocks letters and numbers as separate sets rather than a single combined kit, so choose a letter set, a number set, or both depending on the marking job.

Heavy duty sets

Heavy duty letter and number sets use a more robust stamp body suited to repeat striking in production and batch-marking environments, where a standard-duty stamp would see faster wear.

Low stress and low stress dot sets

Low stress (low shock) sets use a stamp geometry designed to reduce the concentration of stress around the struck impression, which lowers the risk of the impression becoming a crack-initiation point in fabricated components under load. AIMS also stocks a dot-style low stress variant for both letters and numbers, which forms the character from a series of punched dots rather than a single continuous stamp face.

Reverse sets

Reverse sets strike a mirror-image character, used where the finished mark needs to read correctly from the opposite face of the material — for example embossing work in leather, plastic or timber, or die and mould marking.

Type-in font set with holder

The 100-piece type-in font set is supplied with its own holder, letting characters be pre-loaded and aligned before striking — useful for longer runs of text or repeated identical markings in the 3–5 mm range.

25 mm letter set and stamp holder

For large-format work AIMS stocks a dedicated 25 mm letter set. A separate hand metal stamp holder is also available — it keeps the stamp perpendicular and steady against the workpiece, which improves impression consistency and reduces the risk of a glancing hammer strike.

Choosing the right character height

Character height is the main selection factor and should be matched to the reading distance and the size of the component being marked:

• 1–3 mm: fine marking on small components, precision parts and instrument work
• 4–6 mm: the most common range for general workshop part numbering, tool ID and equipment tagging
• 8–12 mm: asset register and equipment marking that needs to be read from a short distance
• 15–25 mm: large-format structural and asset marking where visibility from further away matters

Within any given set, also match the stamp variant to the job: standard for general use, heavy duty for repeat production runs, and low stress (or low stress dot) where the marked component will be under structural or cyclic load.

Material and hardness notes

Gravurem stamps are manufactured from hardened tool steel to give a durable, wear-resistant striking face for marking mild steel, aluminium, brass and other common workshop materials. As with any hardened punch, the workpiece needs to be softer than the stamp face — attempting to stamp a material harder than the stamp itself will deform or chip the stamp rather than mark the work. For stainless steel and hardened or case-hardened components, expect faster stamp wear, and for very hard or hardened surfaces an alternative marking method (such as engraving) may be more appropriate than hand stamping. AIMS's team can help match a stamp variant to your material — contact us with the job details.

Applications

Hand stamp sets are used wherever a permanent, legible mark is needed on a physical part or component:

• Engineering and fabrication: heat number transfer and material traceability marking, where AS/NZS 5131 fabrication and erection requirements call for material traceability through to the finished component
• Asset and equipment ID: plant, tooling and equipment marking for maintenance and asset registers
• Workshop and tool marking: ownership and identification marking on hand tools and fixtures
• Automotive: chassis and engine number stamping for compliance and restoration work
• Jewellery and metal craft: decorative and personalised marking on small metal pieces
• Trade training: apprentice and workshop skills marking exercises

Brand

AIMS Industrial's hand stamp range is supplied by Gravurem, a manufacturer of metal hand stamps, letter and number sets and marking accessories for permanent identification marking of metal, plastic and other materials, machined to consistent tolerances for clear, repeatable impressions.

Companion ranges

Hand stamping is one part of a broader marking and identification toolkit. See also our marking & scribing tools for paint markers, scribers and layout tools; punches & punch sets for centre and pin punches used alongside stamps; identification products for the wider asset-marking and tagging range; hand tools for general workshop hand tools; and safety equipment & PPE — eye protection is recommended whenever striking hardened steel stamps, as a chipped stamp fragment under heavy strike is a genuine eye injury risk.

Hand stamp set FAQs

What size hand stamps should I use for general workshop marking?

4–6 mm is the most common range for general part numbering, tool ID and equipment tagging — large enough to read at a glance and small enough to fit most component faces. Use 1–3 mm for fine or small-component work, and 8 mm or larger for asset marking that needs to be read from a short distance.

What's the difference between standard, heavy duty and low stress sets?

Standard sets suit general workshop marking. Heavy duty sets use a more robust stamp body for repeat striking in production or batch-marking work. Low stress (low shock) sets use a stamp geometry that reduces stress concentration around the impression, which matters for components that will be under structural or cyclic load.

What is a "dot" style stamp set?

A dot-style stamp forms the character from a series of punched dots rather than one continuous stamp face. AIMS stocks dot-style sets in the low stress range for both letters and numbers.

Can hand stamps mark hardened steel or stainless steel?

They can mark stainless steel, but expect faster stamp wear than on mild steel. As with any hardened punch, the workpiece needs to be softer than the stamp — a component that has been hardened or case-hardened is likely to be too hard for a hand stamp to mark cleanly, and an alternative method such as engraving is usually more suitable.

Why are number sets 9 pieces and letter sets 27 pieces?

This is a long-standing trade convention. A number set covers digits 0–9 in 9 pieces because the "6" stamp doubles as a "9" when rotated 180°. A letter set covers the 26-letter alphabet plus an ampersand (&) in 27 pieces.

Does AIMS sell combined letter-and-number sets?

Our letter and number sets are sold separately rather than as a single combined kit — pick a letter set, a number set, or both, in matching or different sizes and variants as your job needs.

What is a reverse stamp set used for?

Reverse sets strike a mirror-image character, used where the finished mark needs to read correctly from the opposite face of the material — for example embossing in leather, plastic or timber, or marking dies and moulds.

What's included in the type-in font set?

It's a 100-piece set supplied with its own holder, so characters can be pre-loaded and aligned before striking — useful for longer text runs or repeated identical markings in the 3–5 mm range.

Do I need a stamp holder, and what does it do?

A stamp holder keeps the stamp square and steady against the workpiece while you strike it, which improves impression depth and consistency and reduces the risk of a glancing or misaligned hammer blow. AIMS stocks a hand metal stamp holder as a standalone accessory.

What hammer should I use with hand stamps?

A single, firm blow from a solid hammer gives the cleanest impression — multiple light strikes tend to shift the stamp slightly and blur the character. Match the hammer weight to the stamp size and the hardness of the material being marked.

Do I need safety glasses when using hand stamps?

Yes. Hardened steel stamps can chip under a heavy strike, and a chipped fragment travelling at speed is a genuine eye injury risk — safety glasses or other eye PPE should be worn whenever striking stamps.

Does material traceability marking on structural steel need a specific stamp type?

AS/NZS 5131 fabrication and erection requirements call for material traceability — typically transferring the mill heat number from the parent plate or section onto the fabricated piece. A low stress stamp is generally the safer choice for this kind of structural marking, since it reduces the risk of the stamped mark becoming a stress-riser in a load-bearing component.
